Test whether the mouse is in the window, and the left of the mouse
The following is given the method of tracking whether the mouse is in the window.
First, use setCapture (), onMousemove (), etc. to determine the mouse position
/ / Set a status amount is used to record and identify if the mouse is in the window
// Bool M_BoverControl;
Void C ????? :: onmousemove (uint nflags, cpoint point)
{
CSTATIC :: OnMousemove (nflags, point);
// If the mouse is still in the window
IF (m_boverControl)
{
CRECT RECT;
GetClientRect (Rect);
// The mouse position left the client area, relieve the mouse capture, and rewrite the status amount m_boverControl
IF (! Rect.ptinRect (Point))
{
m_boverControl = false;
Releasecapture ();
// ......
// Operation when other mice leave
// EG: RedRawwindow ();
Return;
}
}
// If the mouse enters the window, check the mouse capture, status parameters
Else
{
m_boverControl = true;
//
// Operation when other mice enter
// EG: RedRawwindow ();
SetCapture ();
}
}
Second, send WM_MouseEleave messages when using trackmouseevent () to leave the window
Use TrackMouseEvent () to determine the mouse stay and send WM_Mousehover messages
/ / Set a status amount is used to record and identify if the mouse is in the window
// bool m_bmousetracking;
// Test a mouse mobile message
Void Csomew :: OnMousemove (uint nflags, cpoint point)
{
// Receive WM_MOUSEMOVE, and m_bmousetracking is a false, the mouse enters the window.
// Set _trackmouseevent
IF (! m_bmousetracking)
{
TrackMouseEvent TME;
Tme.cbsize = sizeof (trackmouseevent);
/ / Monitor the mouse to leave
Tme.dwflags = TME_LEVE;
Tme.hwndtrack = this-> m_hwnd;
IF (:: _ TRACKMOUSEEVENT (& TME))
{
m_bmousetracking = true;
//
// Operation when other mice enter
//
}
}
CView :: OnMousemove (NFLAGS, POINT);
}
//
/ / Treat WM_MOUSELEAVE message
//
// message processing function declaration
AFX_MSG LRESULT ONMOUSELEAVE (WPARAM WPARAM, LPARAM LPARAM);
// message mapping
ON_MESSAGE (WM_MOUSELEAVE, ONMOUSELEAVE)
// Processing function definition
LResult Csomewnd :: OnMouseLeave (WParam WPARAM, LPARAM LPARAM)
{
//
// Operation when other mice leave
//
// Reset status quantity
m_bmousetracking = false;
Return True;
}
